So, just to confirm, you are running the latest beta version of CAVE, 
20.3.2-0.3?

We have encountered this issue before, almost exclusively on Windows OS, and I 
thought we 
had completely fixed it for all Operating Systems with our latest release of 
the beta.

But, if you're still experiencing this issue, you should be able to resolve it 
by disabling
IPv6 connections on your machine.  These are the steps you would follow:

. Disable IPv6:
. 1. Navigate to System Preferences from the top left Apple dropdown or 
Spotlight Search.
. 2. Go to Network and select ‘Advanced…’.
. 3. Click the second tab – TCP/IP – and locate the Configure IPv6 dropdown.
. 4. Select Link-local only from the dropdown.
. 5. Click OK to save your changes, then restart your Mac.
.
. Clear caveData and restart CAVE:
. 1. Close CAVE
. 2. Remove caveData 
(http://unidata.github.io/awips2/appendix/common-problems/#removing-cavedata)
. 3. Restart CAVE (and connect to whatever site you choose)

Please let me know if that solves your issue?
Thank you.
